Different Pattern of Inflammatory and Atrophic Changes in the Gastric Mucosa of the Greater and Lesser Curvature.

2015


 
 
 
 
 
 Background & Aims: Appropriate biopsy sampling is important for the classification of gastritis, yet the extent of inflammation and atrophy of different regions of the stomach with chronic gastritis have been addressed only in a few studies. The aim of our study was to analyze the inflammatory, atrophic and metaplastic changes in the greater and lesser curvature of the antrum and corpus mucosa.
 Methods: 420 patients undergoing upper endoscopy were enrolled in the study. Four expert gastrointestinal pathologists graded biopsy specimens according to the updated Sydney classification.
 Results: The obtained results showed that the mononu…

Causal relationship of hepatic fat with liver damage and insulin resistance in nonalcoholic fatty liver

2017

Abstract Background and Aims Nonalcoholic fatty liver disease is epidemiologically associated with hepatic and metabolic disorders. The aim of this study was to examine whether hepatic fat accumulation has a causal role in determining liver damage and insulin resistance. Methods We performed a Mendelian randomization analysis using risk alleles in PNPLA3, TM6SF2, GCKR and MBOAT7, and a polygenic risk score for hepatic fat, as instruments. We evaluated complementary cohorts of at‐risk individuals and individuals from the general population: 1515 from the liver biopsy cohort (LBC), 3329 from the Swedish Obese Subjects Study (SOS) and 4570 from the population‐based Dallas Heart Study (DHS).

C4BQ0: a genetic marker of familial HCV-related liver cirrhosis

2004

Source Department of Medicine and Pneumology, V Cervello Hospital, Via Trabucco 180, 90146 Palermo, Italy. lindpas@yahoo.it Abstract BACKGROUND AND METHODS: Host may have a role in the evolution of chronic HCV liver disease. We performed two cross-sectional prospective studies to evaluate the prevalence of cirrhosis in first degree relatives of patients with cirrhosis and the role of two major histocompatibility complex class III alleles BF and C4 versus HCV as risk factors for familial clustering. FINDINGS: Ninety-three (18.6%) of 500 patients with cirrhosis had at least one cirrhotic first degree relative as compared to 13 (2.6%) of 500 controls, (OR 7.38; CI 4.21-12.9). C4BQ0 was signifi…

Genesis of variant Philadelphia chromosome translocations in chronic myelocytic leukemia.

2003

The Philadelphia (Ph) chromosome is found in more than 90% of chronic myelocytic leukemia (CML) patients. In most cases, it results from the reciprocal t(9;22)(q34;q11), with the ABL proto-oncogene from 9q34 fused to the breakpoint cluster region (BCR) locus on 22q11. In 5%-10% of patients with CML, the Ph chromosome originates from variant translocations, involving various breakpoints in addition to 9q34 and 22q11. In our investigation, three CML cases with complex Ph translocations have been analyzed by G-banding and fluorescence in situ hybridization (FISH). FISH with breakpoint-spanning probes for the BCR and ABL genes revealed information about the genesis of complex Ph translocations.…

The extent of HLA-DR expression on HLA-DR+Tregs allows the identification of patients with clinically relevant borderline rejection

2013

Regulatory T cells (Tregs) were shown to be involved into the pathogenesis of acute rejection after transplantation. The suppressive activity of the total regulatory T cell pool depends on its percentage of highly suppressive HLA-DR(+) -Treg cells. Therefore, both the suppressive activity of the total Treg pool and the extent of HLA-DR expression of HLA-DR(+) -Tregs (MFI HLA-DR) were estimated in non transplanted volunteers, patients with end-stage renal failure (ESRF), healthy renal transplant patients with suspicion on rejection, due to sole histological Bord-R or sole acute renal failure (ARF), and patients with clinically relevant borderline rejection (Bord-R and ARF). Compared to patie…

Effects of immunosuppressive drugs on the cognitive functioning of renal transplant recipients: A pilot study

2011

Some renal transplant patients show cognitive, emotional, and behavioral changes as part of possible neurotoxic effects associated with immunosuppressive medication, especially tacrolimus. This study evaluated effects of immunosuppressive drugs on some cognitive tasks. Patients treated with sirolimus and cyclosporine reported some of the noncognitive side effects related to immunosuppressive treatment. We observed attention and working memory impairment in patients treated with sirolimus or tacrolimus. Performance of cyclosporine-treated subjects was similar to that of healthy volunteer controls. Since the mood, anxiety, and sleep patterns measured were unaffected, it could be concluded tha…

The new HFA/ICOS risk assessment tool to identify patients with chronic myeloid leukaemia at high risk of cardiotoxicity

2022

AimsTyrosine kinase inhibitors (TKIs) used to treat chronic myeloid leukaemia (CML) can cause cardiovascular adverseevents. So far, the Systematic Coronary Risk Evaluation (SCORE) charts of the European Society of Cardiology (ESC) have beenused to identify cancer patients at increased cardiovascular risk. The primary aim of our study was to evaluate the usefulnessof the new cardiovascular risk assessment model proposed by the Cardio-Oncology Study Group of the Heart Failure Associ-ation (HFA) of the ESC in collaboration with the International Cardio-Oncology Society (ICOS) to stratify the cardiovascular riskin CML patients, compared with SCORE risk charts. The secondary aim was to establish…

HLA-DRB1*1301 AND *1302 protect against chronic hepatitis B

1997

Abstract Background/Aims: The outcome of acute hepatitis B infection may be influenced by host factors like the major histocompatibility complex (MHC). We have investigated MHC class I and class II antigens in patients with chronic hepatitis B compared to a healthy control population. To confirm the findings of this first study we performed a second study in a group of subjects who had spontaneously recovered from acute hepatitis B infection. Methods: Frequencies of MHC class I and class II antigens were analyzed in patients with chronic hepatitis B virus infection and in control subjects. MHC class I typing was done by standard microlymphocytotoxicity assays. DRB1 and DQA1 genotypes were d…

Monosodium benzoate hypersensitivity in subjects with persistent rhinitis

2004

Background:  Very few data are available from the literature on whether nonatopic subjects affected by persistent rhinitis may show the appearance of objective symptoms of rhinitis after the ingestion of food additives such as tartrazine (E102), erythrosine (E127), monosodium benzoate (E211), p-hydroxybenzoate (E218), sodium metabisulphite (E223), and monosodium glutamate (E620). It is still unclear whether the ingestion of food additive may cause, as well, a consensual reduction of nasal peak inspiratory flow (NPIFR). Therefore, we used a double-blind placebo-controlled (DBPC) study to evaluate this hypothesis. Patients and methods:  Two hundred and twenty-six consecutive patients (76 male…
